To change a closed ticket, you must first locate the ticket. In the Cash Register / Cashier section, you can change the view to Close Tickets by selecting View on the left hand side menu, and select Closed Tickets.

Once you find the ticket you want to change, open the ticket by double clicking the ticket or click Adjust from the buttons at the top. The adjust dialog will allow you to alter items, change customer or reprint sales slips.

To adjust payment details or ticket date, click the Adjust Tenders button on the bottom right. The next dialog will allow you to adjust payment amounts and also the closing date of the transaction. The date is in the top right hand corner.

If you change the payment details, they must zero out. If the ticket is not balanced, the unbalanced amount will appear in red.

Once you are done altering the ticket, click Ok to save.
